POST-DOCTORAL RESEARCH POSITION IN EXPERIMENTAL MATERIALS SCIENCE

School of Engineering and Applied Sciences, Harvard University

The Harvard School of Engineering and Applied Sciences seeks highly qualified applicants for a post-doctoral research position in experimental materials science.  The successful candidate will participate in a project to design an apparatus for high-temperature calorimetry on nanoscale quantities of materials. This apparatus will be used to study phase transformations in complex ternary and quaternary materials systems.

any idea about boundary conditions to be used when modelling a unit cell of a foam

Submitted by pthiyaga on

Dear friends / distinguished imechanicians,

I am trying to use micromechanics in  foams to numerically compute the elastic constants using one unit cell. I see some literature available when simple unit cell shapes are assumed (like cubical or hexagonal). However there is nothing specific about modelling for tetrakaidecahedral foams. Assuming the right boundary conditions would be critical for computing the constants. I am not able to come up with a reapeating pattern for determining the places to apply the boundary conditions.

Abaqus: How to display a new tensor define by myself in vumat?

Submitted by Wang Guofeng on

Hi, all

I am writing one code of vumat. I want to know how to display the contour of a new tensor define by myself in vumat.

It is seems that we can use SDV to realize this in UMAT. But in vumat, how to display the results in the post processor of abaqus?

thanks

ABAQUS UMAT

Submitted by alper_tastan on

Hello;

In my graduation project, the instructor wanted from me to work the
UMAT Subroutines in ABAQUS. I am looking for someone who can help to me
about this issue. I really got an urge for completin this project and
really need of somebody's help.

From now am thanking to the ones who will help to me.

I am lettin my msn adress for the ones who want to contact with me...:
